Abstract
A small multilayer filter, in which a phase shifter may be constituted without increasing overall size of the filter. The overall size may be reduced without deteriorating the characteristics. Above the open end of a plurality of strip lines 4A provided on a dielectric layer 4, a coupling sector 3A of input/output pattern is placed to face it with a dielectric layer 3 interposed. An inductance L1, L2 is formed by connecting a side electrode 7A, 7B with a continuity sector 3B of input/output pattern; and said side electrode 7A, 7B with an input electrode 8A, output electrode 8B, respectively, by means of an electrode pattern 5A.
